for future reference, idk what youre using, but winrar and 7zip both have a feature to remove redundant folders while extracting, so using "Extract to folder..." should always result in a consistent "folder -> files" structure, instead of "folder -> folder -> files" or "files loosely"
whatever kde plasma is using by default also reportedly does that? so if youre on loonix, it should be ok as well
if its not on by default (for some godforsaken reason), it shouldnt be too hard to find the config or something and just flip it over
should solve your issue for good
